Grade one filter 2 is important preprocessing device, its effect is by tiny in filtering and Adsorption raw water
The impurity such as particle, suspended matter, colloid, organic matter guarantee that it is discharged SDI pollution index < 5.Water part is set to suspend by it
Object, organic matter and colloid become micro-floccule and retain and remove in anthracite filtering layer 3 and quartzy sand filter blanket 8.Overall characteristic is energy
It is enough effectively removed colloid, suspended matter and organic matter very sensitive to resin in raw water, the requirement to water inlet is low, and water outlet is steady
It is fixed.To adapt to the special natural environment of off-lying sea, filter housings material uses 316L stainless steel, wall thickness 8mm, diameter
2616mm, high 4850mm, anthracite thickness 700mm in filtrate, partial sizeQuartz sand thickness 800mm, grain in filtrate
Diameter Design pressure is 0.60Mpa, wears cathode protection device, prevents electrochemical corrosion, filter runs one section
It is backwashed after time, backwash intensity 16l/m2·s。
Using secondary filter 10 can by without the water of purification such as: rainwater, river water, lake water are directly changed into limpid height
The drinking water of quality,
10 filtrate of secondary filter uses huge sum of money stone ultra-fine grain homogeneous filtering material, density > 4.2T/m3, partial size 0.18~
0.27mm, due to its unique water distribution and rainwater catchment, can make filtering velocity degree reach 20 gallons/(dividing square feet) without influencing
Filter effect can make delivery turbidity be maintained at 0.5NTU hereinafter, giardia lamblia stiles and Cryptosporidium can be effectively removed.Second level
It is additionally provided with backwash automatic pressure unit inside filter 10, is adapted to the work system of low-pressure, and does not need additional
Increase backwash gas source or water source, saves the equipment investment expense of user convenient for user's daily management.1~3 need to be only rinsed every time
Minute can rinse booty well, and backwashing water uses the filtered clean water of other tanks.Its main feature is that: on the one hand not
Filter operation is interfered, guarantee system uninterruptedly supplies water；On the other hand using the filtered clean water of other tanks as backwash water source,
It is effective that dirty water is prevented to flow back into filtration system, backwash water 1.02m3/min.Former electricity occurs when to avoid contacting with water for a long time
Pond corrosion, each secondary filter 10 are provided with cathode protection device, and all metal portions can be effectively protected in each cathode
Part does not corrode because of electrochemical rust and spuious Faradaic current, equipment is used for a long time still bright as new.The utility model uses
The secondary filter 10 of three can system, single tank is having a size of 916 × 1850mm of Φ, and shell 316L stainless steel material, shell wall thickness is not
Less than 6mm, delivery turbidity < 0.5NTU.Filtered water is uniformly flowed by hydraulically balanced water distributor 18 and nozzle 21
In tank, so that the pressure loss of water flow water when passing through secondary filter 10 is very small, the turbulent phenomenon of water flow is greatly reduced,
And water flow is almost completely perpendicular through filter media surface, is more than 0.81m in the rate of filtration3/min/m2In the case where, mistake
Filter medium surface is not in any groove.In the case where high-rate fitration, the band of the solid impurity that need to be stopped in water flow
Attempt to penetrate filter medium under dynamic, 10 bottom of secondary filter can stop grain by the collector pipe 19 with taper gully-hole
The filter medium of diameter very little.Water (flow) direction reversing is passed through into filter when backwash process.It is between multiple secondary filters 10
Source water, backwash valve movement are provided to the tank body that needs recoil using the filtered water purification of other tank bodies, water purification passes through tank body bottom
The receipts water system in portion enters tank body and starts to backwash, and the reverse water flow into tank is by rush fluffy of filter medium and discharges
The dirt of attachment thereon, discharges outside the tank it with water flow.
Tertiary filter 13 is using macrovoid active carbon as filtrate, and specially shell-shaped active carbon, utilization is macroporous
Part iron tramp in the suspension granule foreign and colloidal impurity and water of the layer of charcoal retention overwhelming majority, to extend filter cycle,
The young quartz sand layer that small particle is arranged below shell-shaped active carbon then can ensure that last filtering effluent quality, reach reduction turbidity
Purpose, active carbon can adsorb remaining organic matter in water, guarantee that water outlet reaches national emission standard.It is special to adapt to off-lying sea
Natural environment, the shell material of tertiary filter 13 use 316L stainless steel, wall thickness 8mm, diameter 2616mm, high 4850mm,
Filtrate thickness 1500mm, design pressure 0.60Mpa wear cathode protection device, prevent electrochemical corrosion.
Grade one filter 2,13 filter of secondary filter are backwashed after operation a period of time, backwash intensity 16l/
m2S, backwash water source come from clear water reserviors 17, and backwashing pump 15 is arranged in clear water water supply pump house, and backwash is emitted into
Gutter, the backwash cycle of grade one filter 2 are to come out in fact into pressure sensor impression disengaging differential water pressures and the accumulative of time
It is existing.
Off-lying sea Rainwater Quality is preferable, can reach requirement after the rainwater purification to ensure long-time storage, in level-one
Coagulant tank 1 is arranged before intaking in filter 2, for removing large granular impurity in water removal；It is arranged one before tertiary filter 13 is intake
First chlorine dioxide pharmacy jar 11 carries out disinfection processing to the water outlet of secondary filter 10, guarantees 13 effluent quality of tertiary filter
It can be up to standard；Rainwater purification apparatus water outlet is stored to clear water reserviors 17, and to guarantee water quality in clear water reserviors 17, dedicated binary form is arranged
Finished product disinfection by chlorine dioxide tank sterilizes, it is ensured that water quality meets " Drinking Water health mark in clear water reserviors 17 for 17 dosing of clear water reserviors
It is quasi- " it requires.
In the present embodiment, grade one filter 2, secondary filter 10, tertiary filter 13 are respectively provided with multiple, multiple level-one mistakes
Filter 2 is in parallel, and multiple secondary filters 10 are in parallel, and multiple tertiary filters 13 are in parallel.It is alternative when processing water is larger
Open up multiple filters.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, if the method concept of the utility model and the various improvement of technical solution progress are used, or without
Improvement directly applies to other occasions, both is within the protection scope of the present invention.
